Some men make a womanish complaint that it is a great misfortune to die before our time. I would ask what time? Is it that of Nature? But she, indeed, has lent us life, as we do a sum of money, only no certain day is fixed for payment. What reason then to complain if she demands it at pleasure, since it was on this condition that you received it.
That man is guilty of impertinence who considers not the circumstances of time, or engrosses the conversation, or makes himself the subject of his discourse, or pays no regard to the company he is in.
This is the truth: as from a fire aflame thousands of sparks come forth, even so from the Creator an infinity of beings have life and to him return again.
